High-energy electronic excitations in La3Ni2O7 by time-resolved optical spectroscopy

Junzhi Zhu, Mengwu Huo, Yubin Wang +11

Recently, high-temperature superconductivity has been established in bilayer La3Ni2O7, which exhibits a density-wave (DW) transition at ~ 150 K under ambient pressure. The DW order…

Highly Anisotropic Charge Dynamics and Spectral Weight Redistribution in the Trilayer Nickelate La $_{4}$ Ni $_{3}$ O $_{10}$

Zhe Liu, Jie Li, Deyuan Hu +10

We study the $ab$ -plane and $c$ -axis charge dynamics of La $_{4}$ Ni $_{3}$ O $_{10}$ using optical spectroscopy. While a pronounced Drude profile, i.e. metallic response, is observed i…
